MEETING LOCATION AND DATE
|
| |
The Bridging the Gap II workshop will be held September 22–26, 2007, at the John H. Chapman
Space Centre, headquarters of the Canadian Space Agency (CSA), which is located in Saint-Hubert on the outskirts of
Montréal. The Centre, about a 45-minute drive from Montréal-Pierre
Elliott Trudeau International Airport, is conveniently located near downtown Montréal at 6767
Route de l'Aéroport, Saint-Hubert, Quebec, J3Y 8Y9.

PURPOSE AND SCOPE
|
| |
Impact cratering is a fundamental geological process that affects all solar system objects with a
solid surface. The formation of meteorite impact craters involves complicated physical processes
that occur over a wide range of temperatures, pressures, and spatial scales, and consequently a
multidisciplinary approach to research is required to improve knowledge of the cratering process.
The purpose of this workshop is to bring together researchers from various disciplines to address
one of its major outstanding problems: the effect of target properties, such as porosity, volatiles,
and layering, on the impact cratering process. The workshop builds upon the successful
workshop Impact Cratering: Bridging the Gap Between Modeling and Observations,
which was held in Houston, Texas, February 2003. The presentation of ideas and results will be through a combination of
invited and contributed oral presentations, followed by substantial discussion sessions and posters.
In keeping with the concepts of the previous workshop, submitted abstracts must discuss both
modeling/experiments and observations, either in the context of observations necessary to
evaluate target modeling in impact simulations, or how particular observations constrain the
target effects on the impact process.
This workshop will comprise sessions devoted to furthering our understanding of the effect of
target properties on various aspects of the impact cratering process, such as
- initial energy deposition and shock wave propagation,
- impact melting and shock metamorphism,
- shock damage to the target,
- mechanics of complex crater formation,
- excavation and ejecta emplacement (proximal and distal),
- expansion plume evolution, and
- environmental effects.
Workshop sessions will begin in the morning of September 24 through September 26, 2007. Each
session will generally begin with two invited talks of 30 minutes, one by a modeler and one by
an observer, with the remainder of the talks as contributions.
The opening session will include an overview of Bridging the Gap I, with updates on some of the
major questions and tasks covered at that workshop (e.g., the ongoing impact codes validation
effort; databases of terrestrial impact craters; recent and future drilling of impact structures; Deep
Impact).

WORKSHOP DESCRIPTION
|
| |
The workshop will begin with a two-day field trip to the ~50-km-diameter Charlevoix impact
structure, which is about a four-hour drive from Montréal. Workshop participants will depart
from the CSA the morning of September 22 and return to the CSA the evening of
September 23, 2007. Travel to and from Charlevoix and accommodations for the field trip will be
included in the workshop registration. There will be no onsite registration; participants
must register in advance. Further travel and logistical information will be provided with the
second announcement. A formal call for abstracts will also be included in the second
announcement.
